PATENT OF NEW YORK, N. Y.

ICE MAKING AND CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 638,577, dated December5, 1899.

Application filed April 12,1899. Serial No. 712,802. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES E. HARRIS, a citizen of the United States,and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Ice Makingand Cutting Machines, of which the following is a specification.

The object of this invention is the production of a machine by means ofwhich clear ice in small particles of various sizes can be produced forregelation.

The means heretofore used to prepare ice for regelation has producedregelated ice of a cloudy appearance by virtue of the entrappin g of aconsiderable number of air-bubbles between the particles of ice,resulting to a great extent from the ice being cut in particles of toosmall dimensions and also by reason of being exposed to the air whilebeing broken or cut in small particles.

The apparatus which constitutes this invention can produce ice inparticles of various sizes, cut or broken under water, thereby avoidingthe excessive entrapping of air, and the product when regelatedproducing clear we To these ends my invention consists of a revolvingfreezing-cylinder, for the accumulation of ice, and adjustablecutting-tools, operating under Water, to detach the ice in suitablecondition for regelation.

Referring to the drawings, in which like parts are designated by similarletters of reference, Figure 1 shows an elevation of my invention,partly in section on the line C D. Fig. 2 represents an end View with afrag mentary section, taken on the line E F. Fig. 3 is a partialelevation of the frame of the machine with conveyer and extended trough.Fig. 4 shows a plan of Fig. 3. Fig. 5 represents a sectional elevationof the device,taken on the line G H. Fig. 6 shows a fragmentary plan.Figs. 7, 8, 9, and 10 represent details'of the cutting devices.

Referring to the drawings, the freezing-cylinder is shown at E, to whichare secured the long hollow journals cl and d, which turn in thecombined bearings and stuffing-boxes cl and 61 the latter being a partof and cast with the trough F. Glands d d are fitted to thestuffing-boxes to prevent the leakage of water shown in Figs. 3 and 4.

from the trough F. To the ends of the hollow journals (1 and d arefitted glands d d", which fit the stuffing-boxes 61 to secure tightjoints between the pipes 12 and t' and the hollow journals (Z and d,preventing the escape of the refrigerant.

It will be noticed that the trough F constitutes and forms part of theframe or housing for the machine. The side f is concaved and concentricwith the freezing-cylinder E, and it continues under the said cylinderuntil it runs into the plane surface f At f andf straight vertical endsare shown. A straight vertical leg is shown at f which joins with thesecondary trough f for the conveyer R. At the junction of the' leg f andtrough f a concaved plate f is secured by bolts 1, the said plateextending between the ends f and f An inspection of Fig. 5 will clearlyshow that the sides and ends of the trough F are brought above the levelof the plate f which in turn is situated above the cutting-tools q andq, allowing, in the first place, the cuttingtools to operate under waterand preventing the water contained in the trough F from overflow in thesecondary trough f.

To properly carry 0d the particles of ice, the secondary trough f isextended by bolting'to the side f the extended trough R, as

This trough R contains the opening r for delivering the particles ofice. A conveyer R revolves in the tronghf and its extension R, the shaft'2; of said conveyor turningin the j ourual-boxes n, being driven by anysuitable source of power.

At P is shown a shaft with blades P P, &c., turning in journal-boxes P,a pulley P being secured to the shaft and driven by any suitable power.The object of the blades P" P, &c., is to sweep the particles of ice,after being out from the freezing-cylinderE, up the curved plate f andinto the trough 1.

At It is shown a horizontal pipe leading from the pipe g, with its valveg, by means of which the trough is fed with water, the pipe It beingperforated with numerous holes on its bottom side. An outlet 12 isprovided at the bottom of the trough F to drain and clean the same.

To the hollow journal 61 is fixed the spurgear G, which can be driven byany source of power. The said gear communicates its motion to thefreezing-cylinder E.

The bevel-gears H and H, shaft J, and bevel-gears K and I communicatemotion to the shaft M, which in turn actuates at the proper intervalsthe knives q and q.

The gearing is proportioned to rotate the freezing-cylinder E onerevolution while the shaft M makes one-half of a turn.

The shaft M carries grooved cams h by which the cutting-tools are keptin a proper position to cut ice from the freezing-cylinder E during onerevolution of the said cylinder and are then moved out of position fromsaid cylinder for the next revolution, to allow the accumulation of ice,and so on alternately. To secure these ends, one half of the groove ineach cam M is cylindrical and concentric with the shaft M, as shown at ab 0 while the other half of the groove, a e 0 is somewhat flattened andcloser to the center of the shaft M. The forked ends n of the spindle Ncarry pins M, with rollers n, which fit the said grooves, and when theportion a b 0 comes in gear with the rollers n the position of thespindle N",with the set of knives, is not disturbed, and the ice is cutfrom the cylinder; but when the portion a e 0 comes in contact with therollers 02 the spindle N, and consequently its set of knives, is drawntoward the center of the shaft M and away from the cylinder E. Thepositions of the knives are thus alternately against and away from thefreezing-cylinder. The distance between the ends of the spindles NandNis adjusted by the turnbuckle n to gage the ice cut from thefreezing-cylinder at the proper thickness.

The grooved cams M are placed on the shaft M so that one set of knives,as in the holder Q, are against the cylinder, while the knives nextadjacent, as in the holder Q, are away from the same, by which alternatesets of knives cut bands of ice off the cylinder, while the remainingsets of knives allow the revolving cylinder to collect ice.

The knife-holders Q Q" are substantial castings, with the verticalpockets g and feet g reciprocating in the guides V V. Lugs g areprovided for securing spindles N, the said lugs being tied to thevertical walls of the pockets by the ribs q". Openings Q10 are left toinsert nuts 92 for securing the spindles N.

The knives are held in upright positions in the cavities Q, where adjusting-pieces g assist to properly locate and secure them with thescrews (1 This disposition of the knives prevents bending when in useand avoids the tremor consequent to cutting-tools when not properlysecured.

Stuffing-boxes f are cast with the legs f of the trough F, through whichthe spindles N reciprocate.

The disposition of each set of knives is novel, the knives in each setbeing alternately placed on difierent levels with respect to the centerof the cylinder, as shown at q and q, so that the upper level of knivescuts the first strip of ice and the lower level cuts the remainder, theedges of the knives over: lapping to thoroughly clean the cylinder ofice. The overlapping edges of the knives are seen at t t and 25 25 Bythis disposition of the knives plenty of clearance is given to thecutting edges, and the liability of their becoming clogged with ice andbreaking is avoided.

It will be seen that the actions of the knives with respect to therevolving cylinder are automatic in operation.

In Fig. 10 I show a modified form of operating the knives in which theyare continuously held against the revolving cylinder. The constructionis cheaper, and the shaft M, with the cams h is dispensed with. Thespindle N in this modified form is made in one piece, with ascrew-thread 8 working through the threaded lug The hand-wheel S adjuststhe position of the knives with respect to the revolving cylinder E. Theend of the spindle N is turned down and fitted with two collars n andn", which work easily against the lug (1 allowing the spindle N to turnand move the knife-holder.

To operate my device, ammonia or some other refrigerant enters the pipeb, on its passage to the freezing-cylinder E, through the hollow journal(I. The said refrigerant ex pands and produces its refrigerating effecton water adhering to cylinder E. The refrig erant, after expanding inthe freezing-cylinder E, leaves the same through the hollow journal 01and piping 2'. The ice which is frozen on the cylinder is cut from thesame by the knives q q and deposited on the curved plate f where theblades P" P, &c., sweep it into the troughf for the conveyer R to carryit to the opening 1' in the extended trough R, when other machinery isbrought into action to regelate the particles of ice.

Having fully described my invention, I desire to secure by United StatesLetters Patent and claim 1.
